[PATCH v2] staging: lustre: fix pointer declarations

[Zahari Doychev]

This patch fixes pointer declarations from void * to void __user * in order
to remove some sparse warnings. The patch also enables again commented named
initializers for the iovec structures. The corrected pointers are used in
these structures as field member values.

lib-lnet.h:798:48: warning: incorrect type in initializer (different address spaces)
lib-lnet.h:798:48:    expected void [noderef] <asn:1>*iov_base
lib-lnet.h:798:48:    got void *dest
